The E-Plus network was licensed to the E-Plus consortium in 1993. In 1997, the network expansion in Germany was completed with approximately 6,500 base stations up to an area coverage of 98 %. The E-Plus network operates on the basis of the DCS 1800 network, which is a further development of the GSM standard.
The E-network operates on 1800 MHz and has smaller radio cells compared with the GSM network, which results in higher density and thus a larger number of subscribers. This also reduces the power of the mobile stations and the base stations. E-Plus has comparable performance features to the D networks. These include call forwarding with its various modes of operation, such as automatic call forwarding or call forwarding in the busy state when a caller does not pick up or is unreachable; furthermore, call barring, call management and the personal answering machine.
The E-Plus network has international roaming, so subscribers can also be reached in other countries under their personal number. Short message service( SMS), theft protection, fax and data transmission are other basic E-Plus services. Value-added services include information, announcement and switching services.
